BRIEF DESCRIPTION OF THE DRAWINGS

For a more complete understanding of the present invention, the objects and advantages thereof, reference is now made to the following descriptions taken in connection with the accompanying drawings in which:

FIG. 1 depicts a system for secure mobile transactions according to one embodiment;

FIG. 2 depicts a method for secure mobile transactions according to one embodiment; and

FIG. 3 depicts a method for secure mobile transactions according to one embodiment.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Several embodiments of the present invention and their advantages may be understood by referring to FIGS. 1-3.

Embodiments disclosed herein facilitate on-line transactions involving a mobile electronic device.

Embodiments disclosed herein may leverage capabilities of a closed loop system to conduct secure payment transactions without exposing a customer's payment account information (e.g., credit card number) to the merchant while maintaining the data needed to allow the merchant to successfully conduct the transaction.

Because the merchant may not be exposed to the customer's payment information, the merchant's payment card industry (PCI) burden may be reduced.

Embodiments may provide validation and confirmation at multiple steps.

Embodiments may include strong issuer-controlled authentication.

Referring to FIG. 1, a system for secure mobile transactions is disclosed according to one embodiment. System 100 may include customer 110, customer's mobile electronic device 115, merchant 120, and financial institution 140. In one embodiment, acquirer 150, payment network 160, and issuer 170 may all be associated with or under the control of financial institution 140 or a processing partner of financial institution 140.

In one embodiment, mobile electronic device 115 may execute a mobile payment application, a digital wallet, or access issuer 170's website. In addition, mobile electronic device 115 may communicate with merchant 120 using, for example, the mobile payment application, digital wallet, issuer 170's website, etc.

An example of a suitable payment application is ChasePay, provided by JPMorgan Chase & Co.

Customer 110 may interact with merchant 120 using mobile electronic device 115. Mobile electronic device 115 may be any suitable mobile electronic device that may execute a mobile wallet application, access a merchant website, execute a payment application, etc.

In one embodiment, merchant 120 may have a relationship with financial institution 140, such as a merchant-acquirer relationship.

In one embodiment, because acquirer 150, payment network 160, and issuer 170 may be part of, or under the control of, financial institution 140, decision making among these elements may be distributed. For example, acquirer 150 may compare the shipping address to the billing address; may compare the shipping address to the billing address; may compare the location of mobile electronic device 115 to a transaction location (e.g., the location of a point of transaction for merchant 120); may determine if there are suspicious number of deliveries to that email address; may determine if there are a suspicious number of transactions using the payment instrument with multiple merchants; may determine if there are a suspicious number of transactions from different IP addresses using the same payment instrument; may determine if the card is being used on a device with a proxy; etc.

In one embodiment, payment network 160 may be an enhanced payment network that may communicate additional data, such as device data, to the issuer. An example of such a payment network is ChaseNet. In one embodiment, payment network 160 may provide two-way communication from the merchant to the issuer that may provide portions of real-time authorization, portions of non-real time authorization, and combinations thereof. For example, transaction data may be provided in real-time to authorize the transaction, but if a shipping address does not match a billing address, a flag may be provided in real-time, but details on the discrepancy (e.g., the mismatched address) may be provided in due course.

In another embodiment, payment network 160 may provide direct communications between acquirer 150 and issuer 170.

In one embodiment, customer 110 may interact with issuer 170 directly using mobile electronic device 115. For example, mobile electronic device 115 may execute an application (not shown) associated with issuer 170, access issuer 170's mobile website, etc. In one embodiment, issuer 170 may identify and/or authenticate mobile electronic device 115 and/or customer 110 directly.

Referring to FIG. 2, a method of secure mobile transactions is disclosed according to one embodiment. In one embodiment, the method of FIG. 2 may be used, for example, when the issuer and acquirer are part of or under the control of the same financial institution, or a processing partner of financial institution. It should be noted, however, that the embodiment of FIG. 2 is not so limited

In step 205, a customer using a mobile electronic device may contact an issuer with a transaction request using, for example, a mobile wallet application executed by the customer's mobile electronic device.

Device fingerprint data may include, for example, operating system data (e.g., operating system version number, etc.), browser data (e.g., browser, version, etc.), locale data (e.g., country, language, etc.), hardware/system data (e.g., operating system, screen resolution, screen aspect ratio, manufacturer, serial number, SIM card, jailbreak information, etc.), settings data, cookie data, mobile application data, etc. It may further collect data from a mobile wallet application, such as user id and password. Other device data may be used as is necessary and/or desired.

In one embodiment, device location information (e.g., GPS data) at the time of contact may be provided to the issuer.

In step 210, the issuer may identify/authenticate the customer using the information received from the customer's mobile electronic device.

In one embodiment, a time stamp at the time of the authentication may be collected and used to establish a trust period, for calculating credentials and signatures, etc.

In one embodiment, the authentication may be coupled and/or linked to location and time period and other potential variables such as channel, etc.

In one embodiment, the issuer may perform additional checks, such as account take over checks, device jailbreak checks, etc.

In one embodiment, the issuer may generate an identifier, such as a transaction session identifier, for the transaction request. In one embodiment, the transaction session identifier may uniquely identify the transaction. In another embodiment, the transaction session identifier may uniquely identify a session in which the customer is authenticated. In another embodiment, the transaction session identifier may be active for a limited amount of time. The transaction session identifier may include, for example, a server component, a card transaction counter, a time stamp, a combination thereof, etc. In one embodiment, the transaction session identifier may be protected by a message authentication code as necessary and/or desired.

In one embodiment, the issuer may generate a payload that may include the transaction session identifier. In one embodiment, the payload may include additional elements, such as an application identifier for the mobile application, a code, such as machine-readable code (e.g., an optical code (e.g., QR code), version, timing validity parameters, the issuer's customer identifier for the customer, a checksum, etc. Other elements may be provided as necessary and/or desired.

In one embodiment, the issuer may provide the payload and/or transaction session identifier to the mobile electronic device following authentication.

In one embodiment, payment data for the selected, or default, payment device, card, etc. may be retrieved. For example, payment data may include, for example, track 1 and/or 2 data with no CVV, track 1 and/or 2 data with CVV, track 1 and/or 2 data with iCVV, track 1 and/or 2 data with dCVV, simplified chip data with a cryptogram, HCE chip data like with cryptogram, full chip data with cryptogram, etc.

In step 215, the issuer may provide the payload or transaction session identifier, payment data, and/or the mobile electronic device location information to the acquirer.

In step 220, the mobile electronic device may provide the payload or transaction session identifier to the merchant.

In one embodiment, the payload and/or transaction session identifier may be communicated by RF communication (e.g., NFC, Bluetooth, WiFi, etc.). Any other suitable manner for communicating the payload and/or transaction session identifier may be used as necessary and/or desired.

In step 225, the merchant point of transaction may receive the transaction session identifier and/or payload contents from the mobile device. In one embodiment, the merchant point of transaction may verify the integrity of the payload, and may inform the customer that the transaction is being processed.

The merchant (e.g., the merchant backend) may initiate an authorization request and may communicate that request to the acquirer.

In one embodiment, the authorization request may include the transaction session identifier, transaction details, and the merchant point of transaction location. Other information that may be provided include, for example: the application identifier for the mobile application, the code version, timing validity parameters, the issuer's customer identifier for the customer, an identifier for the point of transaction, a transaction amount, transaction details (e.g., items purchased), a merchant transaction identifier, a transaction time, and a signature.

In step 230, the acquirer may receive the transaction request from the merchant. In one embodiment, the acquirer may verify the integrity of the data received from the merchant. In one embodiment, the acquirer may validate the transaction location by comparing the mobile electronic device location received from the issuer to the terminal location.

In one embodiment, if the transaction location is not validated, the acquirer may reject the transaction.

In one embodiment, the acquirer may create an authorization request for the transaction based on the payment data received from the issuer.

The acquirer may pass the authorization request to the issuer via a payment network or any suitable communication channel. In one embodiment, the acquirer and the issuer may communicate directly.

Accordingly, the user interface is any device that provides communication between a user and a processing machine. The information provided by the user to the processing machine through the user interface may be in the form of a command, a selection of data, or some other input, for example.

As discussed above, a user interface is utilized by the processing machine that performs a set of instructions such that the processing machine processes data for a user. The user interface is typically used by the processing machine for interacting with a user either to convey information or receive information from the user. However, it should be appreciated that in accordance with some embodiments of the system and method of the invention, it is not necessary that a human user actually interact with a user interface used by the processing machine of the invention. Rather, it is also contemplated that the user interface of the invention might interact, i.e., convey and receive information, with another processing machine, rather than a human user. Accordingly, the other processing machine might be characterized as a user. Further, it is contemplated that a user interface utilized in the system and method of the invention may interact partially with another processing machine or processing machines, while also interacting partially with a human user.

It will be readily understood by those persons skilled in the art that the present invention is susceptible to broad utility and application. Many embodiments and adaptations of the present invention other than those herein described, as well as many variations, modifications and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and foregoing description thereof, without departing from the substance or scope of the invention.
